In order to keepjapparatus otthis kind clean it is necessary that' it rbe easily taken apart and as such apparatus is usually constructed the f* waterinust first be shut oit trointhe supply by turning a ,valveg- My presenti, apparatus relates to an Varrangement whereby whenever the washer' is in place the main valve will be open and when thev washer is removed the f niainivalve will'be-V automatically shut. y In describing rniy invention l have reierred to it in associa-tion with a tumbler washer, butin using that terni l do notmean to imf ply that it has not other'uses.

listhe pipe leading from the water sup-i` ply. It leads into a chamber 2 foi-ined at the lower end' of'accasting 3,.the bottom of fwhichisclosed by'ca cap 4. This chamberv gives clearance room for myp'valve and valso y serves as a clean-out. c passage 51 through it the upper end ot which y o washer whichincludes thervalve lorI operatl jing it. `'lhepassagev 51 is extended downl ward at a smaller diameter below the thread-y is open and threaded as at 5 to screw on a coupling andkr 'to` receive and support the ed portion and receives the valve stem 6 carryingfat its lower end the valve? whichy 'is provided with a packing 8 and inoves in the i ychamber 2. ThroughA thejcentre of this 'valve stem 6 is a passage v9 and through the walls of the stein are passages 10 which conthe passage. Around a portionoithe valve stem, which fis reduced in dianieter, is a spring l2'theflower end otwhich rests on a] Vshoulder 13 within the passage 51, itsupper stein.`

The washer, which 'for purposesot general 65 'description will be called a iXture,` maybe ofanyl welllnown construction. TheliX? turecompriesthe casing` .15' thelower end of which is threaded vso as tov screw into the threaded opening `5 of the casting 3 andthe r70 upper'end of which is `closed`byaplug 21.

l/Vithin this casing contained a valve 16 and valve rod 17 .which passes up through the1plug p21. Cams lSj'offwell lrnownconl struction formr partof andare operated by levers19', whichy are-pivoted to the valve stem' 17' kand rest upon theupper surfaces'bt l the plug rso 'that the valve beliftedgby depressing the end `o"`t"th"e levers. VAround the *Valve stem is' afspring 20'the upper end 80 of which yabuts against? the under surface of the plug 2l yandthelowere'nd of .which rests on a kshoi'ilder 22'on the'valve stein.` Thisv valve as itis ordinarily utilized :is operated bythe pressure of the glass orother article to be washed upon the`levers19 which presses.

down their outer ends tlius lifting the valve in Va 4manner well known.'

InFig. 2 it will beiseen that when this casy ing 15 is screwed home in thethreaded-por-j tion of the. opening 5 the valve steni-12'will be depressed by the'lower end ofthe casingv L 15 so that water will pass up from the pipe 1 -throughrthe openings 10 and passage 9.1m,-

til itstrikes the under side of the 'valve 16. 95 i `Upon depressing the levers 19 -andthus lifting the valveilG the water passes out through` i' 'the pipe 23y and into the'perforated tubular. i l

ring 24 until thepressure on the levers 19 is removed when the spring 20 closes the valve 16 and shuts,y off the'water.y Upon the unscrewing` and removal of the iixture or casing' 15 for cleaning the valve7 controlling 26 is a saucerlike cas ungwhich is threaded' ,1f 1 f Jfiom above and carries them ofi;A to the Waste. 27 is a Waste pipe which leads oli from the interior of this saucer 26.

I have found the chamber 2 very useful because it is quite frequently the case, especially after a repair job has'been done, that bits of solder or other material are carried into the apparatus by the Water supply and in being Carried on by the current of Water may injure the valve. in the present .case suc-h heavy material Jfalls from the pipe l into the chamber 2 and the crew cap may be removed from time to time and the chamber cleaned.

The advantage of this device Will be readilyunderstood. It not infrequently happens that When the usual Washing device is used, thev operator forgets to turn oii the Water from themain before he unscreivs the liz;-

lture so that a stream ot Water under street pressure flows out fromthe coupling after the fixture is removed. As my controlling yvalve is automatic it gradually closes as the fixture is unscreived so thatv'hen thev lixture is removed, the valve being held in place by the Water pressure of the main there can be no leakage. It will be evident to those skilled. in the art that my invention may be ,otherwise embodied. It will be understood that a device embodying my invention need not necessarily be used in vertical position as sho-Wn so that the Words upper and lower las used in the lclaims relate to the several parts 4as shown in the drawings Where the de,- -vice is in its normal vertical position..

Vhat l claim as my invention is l. The device above described comprising a casting, a chamber therein having a Water inlet and a-passage from said chamber with a valve seat at its lower end, a valve to en- L gage said valve seat, a spring controlled bollow valve stem to operate said valve, said valve stem being longer than said passage, a liXture normally mounted on said casting and having a chamber provided with a Water outlet and an opening connecting said chamber with said passage, a spring controlled valve mounted to close said opening, said iXture .when in place holdingl open said lirst named valve and allowing liquid to pass into said passage'and means tor operating said second spring controlled valve whereby Water may pass to said outlet.

2. A device of the kind described conjiprising' a casing having two chambers, the lower .chamber having a Water inlet and the upper vchamber having a Water outlet, a passage connecting said chambers, a valve seat located at each end et said passage, avalve having a hollow valve stem located in said passage, said valve being adapted to close the valve seat at the lower end of said passage, said valve stein being long-er than said passage, a second spring controlled valve located in the upper chamber and adapted normally to close the valve seat at the upper end of said passage, the part comprising the upper chamber ot-said casing being detachable from the part comprising the lower chamber and when in place engaging the hollow valve stein and holding itsl valve open, in combination With a supporting means for an article to be Washed.
